So I'm using 10.4.7. and I'm using XP on both boot camp and parallels.. thing is, what should my external drives be formatted in? I know XP can't read or write to Mac formatted disks... I think Macs can only read NTFS and FAT 32 can only hold files upto 4GB (A lot of the files I'm transferring are about 6GB. any advice? cheers.
